Hello Turbo world, I have a 93 Miata on a v2 CXRacing turbo kit. My main issue I’m having with tuning is that if I press the pedal past 20% the car acts as if I’ve let my foot off the throttle?? I also cannot get it stop leaning out and I’m sure the throttle position problem is interfering with that as well. Hope to hear back from you guys. This is my first time tuning and am sure I’ve made some simple mistakes in my tune file as well

I'm assuming you have a standalone ecu? If you do, I would check to see if over run fuel cut is turned on and if it's supposed to be on, tuned correctly.

yessir I have a MS PNP 2, it does it on acceleration. It idles great but as soon as I open throttle it’s like it’s not adding fuel, sounds like a misfire or choke up. If I put the pedal all the way down the car will return to idle and then just lean out. If I need to post my current tune I will do so

I would do so anyways.

Did you install a VTPS? Was the car running on MS before adding the turbo bits?

I think it'd be helpful if we could see your tune.
